A fix for possible memory corruption during DM table load, fix a possible leak of snapshot space in case of a crash, fix a possible deadlock due to a shared workqueue in the delay target, fix to initialize read-only module parameters that are used to export metrics for dm stats and dm bufio. Quite a few stable fixes were identified for both the thin-provisioning and caching targets as a result of increased regression testing using the device-mapper-test-suite (dmts). The most notable of these are the reference counting fixes for the space map btree that is used by the dm-array interface -- without these the dm-cache metadata will leak, resulting in dm-cache devices running out of metadata blocks. Also, some important fixes related to the thin-provisioning target's transition to read-only mode on error. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.15 (GNU/Linux) iQEcBAABAgAGBQJSq2pVAAoJEMUj8QotnQNaAzEH/0qpz06SVd3+oTbsWeWxXwax B0zIZ4HPnaD9FDfSWN+6IdQ6Rkn51cspMBHPxWX0I8pmqOTg7MUM7wbaZZaKT3UW aDlibzG1O3zBGbkr+Qhbh89fJK5/3xnZXlK0hOyaNI2vz1rA6RThZ2hIeak9xQYr 7USz2bjSMXchwebb0Z01CrRnOkhUFg6yUJURIEu4XFCJmDM/PM9zKogLGYKuZedK pZePnZhwgkLMn7f9l4lPHk3EcWeD4Nf9WR0lS4eKdbYsvMxm1QE7BpDlVJD0Asjg /SVOVkgygW18TINMHuw1K0DPdSCo5UZF2HRj1QUD/X4N2BSkio+E1qwF6kT4ltk= =0Ix+ -----END PGP SIGNATURE----- Merge tag 'dm-3.13-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper fixes from Mike Snitzer: "A set of device-mapper fixes for 3.13.
